Container Cap Assembly with Magnetic Fixation and Nested Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container cap assemblies have complex coupling structures, making them inconvenient to use and prone to contamination during separation, with a high risk of losing caps and smearing materials on surfaces.
Innovation Solution
A container cap assembly with a simplified design where the inner cap has a flange portion that extends outward and is coupled with an outer cap featuring a protrusion, allowing for single-operation coupling and decoupling, and optional magnetic fixation to prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container cap assembly uses a complex coupling structure to maintain secure attachment, then the reliability of the cap assembly is improved, but the ease of operation deteriorates due to difficult coupling and decoupling processes
Solution Approach 1:
The cap assembly is divided into distinct functional segments: the inner cap with sealing function, the outer cap with structural support, and the flange portion with engagement function. This segmentation allows each component to perform its specific function efficiently while simplifying the overall coupling mechanism through standardized interfaces.
Solution Approach 2:
The inner cap is nested within the outer cap, with the flange portion of the inner cap extending through the outer cap. This nested configuration allows both caps to be attached to the container neck simultaneously while maintaining secure attachment through the threaded engagement of the outer cap and the flange engagement of the inner cap.
2Reliability
If the container cap uses a two-step separation process to ensure proper disassembly, then the reliability of the separation process is improved, but the ease of operation deteriorates due to inconvenience and time consumption
Solution Approach 1:
The flange portion of the inner cap is pre-configured to extend through the outer cap to a position that allows direct engagement with the container neck or removal tool. This preliminary positioning enables the inner cap to be separated in a single operation by pulling the flange portion, eliminating the need for a two-step separation process while ensuring proper disassembly.
3Reliability
If the inner cap is forcibly inserted into the container neck to achieve sealing, then the sealing reliability is improved, but the ease of manufacture deteriorates due to precision requirements
Solution Approach 1:
The sealing function is localized to the flange portion of the inner cap, which is configured with specific dimensional properties (extending beyond the container neck by a predetermined distance). This local quality configuration ensures reliable sealing through the flange's geometric design rather than requiring high-precision insertion of the entire inner cap body.
Solution Approach 2:
The inner cap is designed to be self-aligning during insertion, with the flange portion automatically positioning itself relative to the container neck opening. The elastic restoration force of the inner cap material assists in maintaining the sealed position without requiring high-precision manual or automated insertion processes.
4Adaptability or versatility
If the container cap assembly uses separate inner cap and outer cap components to provide distinct functions, then the adaptability of the cap assembly is improved, but the device complexity deteriorates due to multiple components
Solution Approach 1:
The inner cap and outer cap are merged into a single integrated assembly that functions as one unit during attachment and separation operations. The flange portion connects both components, allowing them to be attached to and removed from the container neck together in a single operation, effectively reducing the operational complexity despite having multiple physical components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and secure coupling and decoupling of the cap assembly, reduces the risk of contamination, and simplifies storage and handling by using magnetic fixation.
Implementation Method 1
the inner cap is configured to be forcibly inserted into the inner surface of the container neck so that an outer diameter thereof is decreased, thereby being closely coupled thereto by elastic restoration force
Implementation Method 2
one end of the support plate, opposite to the other end having the protrusion, is fixed to a container body by a magnet

AI summary
A container cap assembly includes an inner cap coupled to an inner surface and an upper end of a container neck and an outer cap maintaining the coupled state of the inner cap, thereby keeping the inside of a container sealed. The container cap assembly includes an inner cap including an outer wall portion corresponding to an inner surface of a neck of a container and a flange portion extending outward from an upper end of the outer wall portion to correspond to an upper end of the neck. An outer cap has a ceiling covering an upper portion of the inner cap and a side wall portion covering an outer circumferential surface of the neck, the ceiling and the side wall portion being integrally formed. The inner circumferential surface of the side wall portion has female threads corresponding to male threads on the outer circumferential surface of the neck.
